The Story Behind the Story: To comic book fans of a certain age, Rich Buckler was their Rob Liefeld; an artist whose tracings (usually from Jack Kirby or Jim Steranko) frustrated some, and who would never let a decent concept die, no matter how many times it had to be restaged. The story began with Atlas Comics in 1975, where David Kraft & Rich Buckler introduced Demon-Hunter. Like yesterday's feature on Howard Victor Chaykin's Scorpion, Buckler was a hungry and dynamic artist who could have helped Atlas win over Marvel Comics fans. However, the book didn't last beyond a single issue; Atlas' loss proved to be Marvel's gain. Just like Chaykin, they continued their story at Marvel, bringing him into (of all things) a story starring Buckler's Deathlok, who time traveled to the present-day Marvel Universe in Marvel Spotlight #33 (1977) for the sole purpose of meeting the renamed Demon-Hunter, who bore the same powers and origin, simply wearing a redesigned costume.
Although Kraft continued to use Devil-Slayer in the Defenders, Buckler's involvement ended there; perhaps he regretted losing control of his co-creation, because in his self-published 1981 magazine Galaxia he revisited the concept again, this time using the name Bloodwing (but again with the same costume, powers and origin and restoring Demon-Hunter's real name). Unfortunately, Galaxia didn't take off and whatever hope Buckler had for continuing Bloodwing (or completing his origin) was scuttled.
Devil-Slayer is still out there, showing up when (and where) you least expect it.
